Emisphere’s Eligen® Technology


Emisphere has created a broad-based proprietary oral drug delivery platform known as the Eligen® Technology which makes it possible to avoid injections for drug administration. The Eligen® Technology facilitates the absorption of small and large molecules without altering their chemical form, biological integrity or pharmacological properties.


Through the Eligen® system, delivery agents or "carriers" facilitate or enable transport of therapeutic molecules, including large peptides and proteins, across biological membranes such as those of the gastrointestinal tract, allowing the drugs to exert their desired pharmacological effect. The delivery agents have no known pharmacological activity in the amounts used to enhance oral drug delivery and therefore may be considered excipients.


The Eligen® Technology uses passive transcellular transport to enable drug molecules of all sizes to cross cell membranes. This is a unique and important feature of Eligen® not shared by other oral drug delivery systems currently available. Once the drug and paired carrier leave the gastrointestinal lumen and reach the intracellular space, they disassociate. This leaves the drug free to pass directly to the circulation and exercise its intended pharmacological action. The carrier is promptly eliminated by normal excretion pathways. Studies have shown that this process does not involve chemical modification of the drug molecule and the integrity of gastrointestinal absorptive cells is maintained.
